The flights will be offered three days a week, starting in November.
Porter has heretofore offered flights between Montreal and Las Vegas with at least one connection at Toronto’s Billy Bishop Airport en route.
Offered on Thursdays and Saturdays as of Nov. 2, the airline’s seasonal, direct flights will take about six hours.
“This is a new gateway to Nevada,” Aéroports de Montréal vice-president Karl Brochu said in a statement. “We are pleased to support Porter in expanding its Montreal service offering to meet the needs of a wide range of travellers.”
